Company Overview: The Engineering-First Manufacturer
Qingdao Inside Industry Co., Ltd. (Inside Metal Fab) is an ISO 9001:2015–certified metal fabrication company based in Qingdao, China. Its integrated facility combines CNC machining (3/4/5-axis), precision sheet-metal (laser cutting, bending, welding) and progressive stamping under one quality system. The company has over a decade of export experience to 20+ countries, serving Tier-1/2 OEMs in sectors like aerospace, automotive, medical, etc. It supports single-piece prototypes up to high-volume runs (no MOQ from 1 to 100,000+ parts). All processes follow robust QA/QC: every lot is inspected on a Hexagon CMM, with First Article (FAI) reports, material test reports (MTRs) and RoHS/REACH declarations provided by default. Compliance with ISO 9001 (a globally recognized quality management standard) and AWS welding codes (D1.1/D1.2) underscores its focus on traceability and reliability.

Company Overview: The Engineering-First Manufacturer
Who We Are
The Inside Advantage: We Optimize, Not Just Execute
Most factories receive a drawing and run it. We read the drawing and improve it first.
Our engineers conduct a systematic DFM (Design for Manufacturability) review on every new project — identifying tolerance stack-ups, unnecessary features, and material substitution opportunities before production begins. Clients routinely achieve 15–25% cost reductions and 20–30% lead time improvements by acting on our DFM feedback.
